[SDL] Perfomance problem with SDL+OpenGL

[Phantom Lord]

Hi, I'm still developing the PhantomSDL library =P, but I stil have
perfomance problems =S...
AFAIK, iterators are most quick and best way to iterate a list (I don't get
very well with the STL...).

So, here is the code that gives me problems:

Instance Handler, Step Function:

std::list<PhantomSDL_CINSTANCE*>::iterator i;
    for(i = mInstances.begin(); i != mInstances.end(); i++)
        {
        if( (*i) == NULL)
            {
            mLog->write(2,"[CInstanceHandler]-> NULL pointer avoided.");
            continue;
            }
        (*i)->stepEvent();
        if( (*i)->getVisible() ) (*i)->drawEvent();
        }


Every stance that can be "instanced" in the Instance Handler, inherits from
PhantomSDL_CINSTANCE.
So then, the drawing event of each instance may vary, but when rendering
nothing, i do get no more than ~400 fps (focused window, 800x600x32).

This is when rendering with SDL.
When rendering with OpenGL...in the same circumstances, i get no more than
~80 fps (focused window, 800x600x32).

Can somebody tell me if this is a problem of my code, or whatever.

BTW, I have a GeForce FX 5500 256 videocard.

Thx!
Cya
